Completed Super Saiyan Blue.
Its empty aura,—with all of its energy having been drawn in and concentrated within the flesh,—is devoid of any visual distractions, which, ironically, emphasizes Goku and Vegeta when on-panel, far more than Blue's aura did. Its calm and reserved, yet explosive energy and fury is the perfectly oxymoronic blend of its progenitors: Super Saiyan and Super Saiyan God, representing a surpassing of the realm of the god. And, unlike the anime, in which Blue is the default, when Complete Blue is unleashed, the action noticably jumps up by orders of magnitude, highlighting the depth of the infinite strength only achievable through divine power in a way that Toei and Toyotaro are normally incapable of; very Toriyama-esque.
It's sick.
